Description
The VNI4140K is a monolithic device made using
STMicroelectronics VIPower technology, intended
for driving four independent resistive or inductive
loads with one side connected to ground. Active
current limitation avoids dropping the system
power supply in case of shorted load. Built-in
thermal shut-down protects the chip from
overtemperature and short circuit. In overload
condition, channel turns OFF and back ON
automatically so as to maintain junction
temperature between TTSD and TR. If this
condition makes case temperature reach TCSD,
overloaded channel is turned OFF and will restart
only when case temperature has decreased down
to TCR. In case of more than one channel in
overload, re-start of the overloaded channels will
not be simultaneous, in order to avoid high peak
current from the supply. Non overloaded channels
continue to operate normally. The open drain
diagnostics outputs indicates over-temperature
conditions.
